(一)package package在我看来就是一个披着.h文件形式的.c文件,他的作用是像.h文件那样用来在top等其它文件中被引用替换,但内容是实打实的,不是一个单纯简单的.h文件那样做点声明就了事,而是切实地可以实现task和function的。 要注意的有两点,(1)package里面不能有assignment,其实要说起来,我觉得如果一个package...

When you declare a class in a package, the package name becomes a prefix to the class name (it could useful to isolate different class/functions/task/etc.. that have the same but serve different functions): Now there are two definitions of class A, one called P::A and the other called...
When we call a task in SystemVerilog, we can’t use it as part of an expression in the same way as we can a function. We should instead think of task calls as being a short hand way of including a block of code into our design. As with functions, we can use one of two methods...
b.在module、class、function、task等地方声明对象: 1 packet my_packet; 2 packet packet_array[32]; 3 long_packet my_l_packet; 1. 2. 3. 对象标识符(my_packet/packet_array/my_l_packet)是例化该对象的句柄(指向对象的指针)。当该对象被创建的时候,该句柄有效,默认情况下句柄将为空(null)。
